SPECIFICATION forming part of Letters Patent N0. 535,122, dated March 5, 1895. Appl cati n filed October 18,1894. Serial No. 526,248. (No model.)

To all whom it may concern: I

Be it'known that we, MARSHALL SATTLEY and ARCHIBALD SATTLEY, of Springfield, in the county of Sangamon and State of Illinois, have invented certain new and useful Improvements in Cultivators. of which the following is a specification.

This invention relates to tongueless, balanced frame straddle row cultivators. It is embodied in the structure hereinafter described and it is defined in the appended claims.

In the drawings forming part of this specification Figure 1 is a perspective representation of a cultivator constructed in accordance with our invention. Fig. 2 is a plan of one side of the front end of the cultivator. Fig. 3 is a rear elevation of so much of the cultivator as is shown in Fig. 2. Fig. 4 is a side elevation of a spindle-bearing draft plate,

showing a draft bar in connection therewith.

The wheels 1 are journaled on spindles 2, which project from the sides of the vertical draft plates 3. The draft plates have hitchholes 3 and also have inwardly turned lugs 8 The brackets, or frames, 9 have horizontal bearings at their forward ends, as indicated at 10. These bearings extend crosswise of the cultivator and receive the ends of arch 15. The bearings are slotted at 11, and pins 12 extend from the arch bar through the slots. Lugs 9, are formed on the rear, outer corners of the brackets 9. They coincide with the lugs of plate 3, and the bolts 4 passing vertically through both sets of lugs form piv oted connections between the bracket and the plates. The beams 14 connect with the brackets by vertical bolts which extend through heads 13 and through the brackets, and provision is made for shifting the beams laterally so as to Vary the distance between them. The draft bars are connected with the draft plates in a manner permitting a limited amount of vertical swing, and they are pro vided with single-trees 17.

The arch connects with the forward ends of the brackets some distance in advance of the wheel spindles and it inclines obliquely upward and forward to an extent sufficient to practically balance the beams and their shovels, &c. To better provide for this result the brackets may extend farther forward and be supplied with additional bearings for the arch, as suggested by dotted lines at 10 in Fig. 2. This will enable the arch to be set forward or back to correspond with the weight of the beams and shovels that may be used in any particular case. The slots 11 extend only short distances around the circumferences of the bearings, about one fourth, and the pitch of the arch holds the pins, or at least one of them, always in contact with the front wall of the slot, Where it, or they, holds the arch from pitching forward beyond its normal incline. By this provision the arch holds the brackets against cross-wise tilting, the brackets hold the arch in its inclined position, and either beam maybe raised and lowered independent of the other without affecting the inclination of the arch.

The draft plate is pivoted, vertically, on the bracket. It carries the Wheel spindle, and it provides for connection with the draft bar, as before specified. The connection of the draft bar with the plate is horizontally stifi, so that when the team turns to one side the plate swings on bolt- 4 and turns the wheel in the same direction.

In practical use the mechanism described is capable of producing desirable results, but to keep the parts in position when the team is detached it is desirable that the wheels be held, yieldingly, at right angles with the transverse axes of the brackets. To effect this result we introduce springs arranged in a manner covered by us in a prior patent, but other arrangements may be substituted therefor without departing from the principle of the invention.

The construction and arrangement of the springs and adj uncts are as follows: The draft plate has pins, or bosses, 5 on opposite sides of its pivot. A head 6 bears against the bosses and has a rod extending across the bracket and through a hole in the upwardly extending lug 9". Spring 8 is placed on the rod, 7,

between the lug and the head, and its tendenoy is to prevent the plate turning from its shown position.

In the drawings, particularly in Fig. i, the draft plate is shown with hitch-holes in both front and rear edges. This is simply to permit the one casting to be used on either side, and is a desirable,but not essential, feature.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. In a cultivator of the class described, the combination of wheels, draft plates bearing rigidly extended spindles for the wheels, brackets hinged vertically to the draft plates and extended forward thereof, an arch having horizontal bearings and a limited amount of rocking play in the front ends of the brackets, cultivator beams hinged vertically to the brackets, and draft bars having horizontally stiff connections with the draft plates and vertical play, substantially as set forth.

2. In a cultivator of the class described, the combination of wheels, draft plates bearing rigidly extended spindles for the wheels,

brackets hinged vertically to the draft plates and extended forward thereof, an arch having horizontal bearings and a limited amount of rocking play in the front ends of the brackets, cultivator beams hinged vertically to the brackets, draft bars having horizontally stiff connections with the draft plates and vertical play, and springs acting between the brackets and the draft plates and tending to hold the wheel spindles at right angles with the brackets, substantially as set forth.

In testimony whereof we sign our names in the presence of two subscribing witnesses.
